Empty taxonomy pages

I am having a taxonomy problem that I can't figure out and my searches haven't helped. Basically, I have created a taxonomy to tag my pages and I can use this field with views etc without any problem. However, when I have created links to those taxonomy terms, the page is coming up as empty (except the term is listed at the top).

If I use /all, then it seems to be working without problem.
So, this works: /taxonomy/term/all
this doesn't: /taxonomy/term/17 (though that term does exist)
this doesn't /taxonomy/term/17/all

In addition, I am using the taxonomy menu module. If I add a new term, it shows up in the menu, but if the counter is enabled, they all show up as "0."

slowly going crazy....

Thanks
